HELMER KINDSTRAND, OF ROCKFORD, ILLINOIS.

HAND-VISIE AND HOLDER THEREFOR.

To all whom t may concern Be it known that I, HELMER KINDSTRAND, a `citizen of the United States, residing at Rockford, in the county of Vinnebago and State of Illinois, have invented certain new and useful Improvements in Hand-Vises and Holders Therefor, of which the following is a specification.

The present invention relates to a hand vise more especially adapted for holding pins and similar work while they are being operated upon, and to a holder or support for the hand vise which will enable the hand vise to he held in rigid position while the work is being operated upon and at the same time permit the hand vise to be moved out of its held position for the purpose of trying the fit of the work, without loosening the bench vise or other means which is holding the hand vise in position. lThe holder for the hand vise is so conigured that the vise maybe readily turned within the holder for the purpose of presenting different sides of the work; and the holder may be said to constitute a bearing for the hand vise in which it. turns. Y

The objects of the present invention are, to provide a holder for the hand vise, which is cheap` and simple of construction, Vand which will provide a irm and rigid support for both the tool and the work; ,and to configure this holder or support so that different sizes of work can be accommodated and supported without any rearrangement of the parts.

A furtherobject of the invention is to provide a hand vise which. is strong and durable of construction, and which will firmly grip work of a relatively large diameter.

The invention further consists in the features of construction and the combination of parts hereinafter described and claimed.

In the drawings, Figure 1 is an elevation of the hand vise and the holder of the present invention, showing the holder clamped by a bench vise; Fig. 2 is a longitudinal sectionv of the hand vise; and Fig. 3 is a perspective of the holder.

The hand vise of theY present invention consists of a handle '4 of any suitable shape and configuration, which has an interiorly threaded sleeve 5 mounted therein, said sleeve being held in the handle by means of a pin 6, or otherwise. The sleeve l5 extends beyond the end of the handle and Speccation of Letters Patent.

Application filed November '7, 1911.

Patented June 18, 1912. Serial No. 658,931.

`outside of the handle is, to all intents and purposes, one end, of the handle, since the sleeve and handle are secured together by the pin 6 so that they are rigidly joined together.

The stem 8 is formed with a screw-threaded end 9, which meshes with the threading of the sleeve 5, and this stem projects a substantial distance beyond the sleeve 5, and has its ends configured to form a slotted head l0. S-lidably mounted upon the stem 8 is a collar 11, which is formed to provide ears 12, between which are pivotally mounted arms 13; and said arms terminate in 4clamping heads 14. Each of the arms 13 is slotted, as-at 15; and entered into the slots and into the slot in the head 10 are toggle members 16, said members being pivotally mounted in the arms 13 and pivotally mounted in the head 10. Interposed ybetween the head 10 and the collar 11 is a tension member 17 for the purpose of maintaining the collar 1n engagement with the end of the sleeve 5, so that said collar follows said handle in its back and forth movements.

The operation of the hand vise is as follows: Vhen the handle 4 is rotated, it advances or recedes along the screw-threaded stem 8, depending upon the direction of rotation of the handle. If a rotative move- `ment is imparted to the handle, causing it to advance along the stem, the collar 11 is moved to-ward the head 10 by such advancing movement of the handle. This imparts a sliding movement to the collar along the stem 8, which carries the arms 13 upward; and since the head remains stationary, such upward movement of the arms will cause the toggle members 16 to swing around their pivotal center in the head 10 in a manner to bring the clamping jaws 14 toward one another. If the handle 4 is rotated in a direction to cause it to recede upon the stem 8, the spring 17 will force the collar 11 backward along the stem in accordance with the backward movement of the handle 4 and sleeve 5, and such backward movement will tend to pull the arms 13 downward, causing the toggle members 16 to swing about their of the togglevmembers will be the rmest and strongest at this point. AThis is d eemed to be of particular moment, since `1n the clamping of large sized work, it 1s frequently a matter of difficulty to obtain a firm and reliable grip upon the work.

As heretofore stated, this hand vise is of a type which is peculiarly adapted for t-he holding of an article of Work such' as a pin. In the manufacture of these pins, it becomes necessary: rst, to obtain a firm rest for the hand vise and work, in order to properly perform the operation of shaping the work; and, secondly, it is necessary to frequently try the pin or other work being formed to determine whether or not it is of the desired shape to fit. It is not always possible to move the article into which the work is to be fitted, and, hence, of course, in order to determine the lit, it is necessary to move the pin.

When any of the old and wellknown appliances, of which I am aware, are used for holding the work iny place, it is necessary, in order to try the fit of the work, to either loosen the bench vise or hand vise, thus requiring a frequent clamping and unclamping of the vise, which takes time and is troublesome. It is furthermore desirable, in forming a pin or like article, to turn the work from time to time, so that all sides of it can be operated upon. This, of course, is impossiblewhere the hand vise is being held in a bench vise.

The rest for the hand vise and work l which I have devised consists of a flat faced' Copies rof this patent may be obtained for bar-like member 18, having its ends bent to provide arms 19 and 20. The arm 19 is configured to have a forked end 21 of a size to fit in the groove 7 of the handle 4, as shown in Fig. 1, forming a rigid support for the handle, but at the same time permitting the handle to revolve within its support. An engaging of the handle in this Ymanner prevents lateral movement of the vise within the holder. The arm 20 has its upper end formed with a groove 22, in which the work clamped by the hand vise is intended to rest, giving the work a'iirm support, but permitting the work to revolve in its support. Thus, the arms 19 and 20 provide rests for the tool and work, whereby the work is given a firm and rigid support during the forming operation, and whereby the vise and tool can be revolved as desired to permit dierent portions of the work to be acted upon. It is obvious that in the construction shown, the vise and work can be removed at will from the holder to permit the pin or other article being formed to be tried from time to time to determine as to its fit. There is preferably a slight amount of play between the handle and forked end, in order to permit of a slight tilting of the tool, which is necessary when work of large diameter is held.

I claim:

' 1. In a device of the class described, the combination of a hand vise, and a holder for said vise, comprising upwardly extending end port-ions and an intermediate body portion, said intermediate portion being adapted to be clamped in a bench vise, the extremities of said end port-ions being congured, said vise having a portion thereof configured in correspondence to the configuration of the extremity of one of said end portions, the extremity of the other end portion being configured to engage the work held by the hand vise, said configured ends forming seats for the hand vise, which permit of its free removal from its holder, and said ends extending upwardly a distance to permit the body of the hand vise to lie clear of the intermediate portion, substantially as described.

2. In a device of the class described, the combination of a hand vise, comprising a handle, jaws, an actuating mechanism for the jaws, and a holder for said vise, comprising upwardly extending end portions and an intermediate body portion, said intermediate portion being adapted to be clamped by a bench vise, the extremity of one end portion being in the form of a fork constituting a semi-circular seat, the handle of the hand vise havingl a circular groove adapted to receive said fork, the extremity of the other end portion being configured to engage the work held by the hand vise, said ends extending upwardly va distance to permit the hand vise to be clear of the intermediate portion, and said ends forming bearings to permit rotation of the hand vise while said holder is clamped in the bench vise, substantially as described.
